My choice of the specific name formosa for this species instead of cubensis 
claims an explanation. I have asked Mr. Maxon to give me his opinion on the 
matter, and I agree with him in his conclusion. Under the original description of 
A. formosum Fér quoted three collector-numbers: LinDEN 2115 (Cuba), LinpEN (should 
be GALEoTT!) 6563 et 6473 (Mexico). Under the description of A. jucundum he quotes: 
Mexico: GaLEoTtT1 6563, Cuba, LinpeN 2115, thus by elimination the name formosa 
should be applied to GaLeort1 6473, which has been done previously by Maxon 
(Contr. U.S. Nat. Herb. 13: 17). But it is certain that F&r’s description of A. for- 
mosum agrees with LinpEN 2115 from Cuba only, not with any Mexican form seen 
by me, and his remarks under A. jucundum and also in Cr. vase. Br. 1: 147 show 
clearly that he distinguished his two proposed species thus: A. jucundum: Les der- 
niers segments aristés, A. formosum: Les derniers segments absolument mutiques; 
écailles jaunatres, rubanées, which differences are clearly described in the two 
descriptions. According to this A. jucundum is no doubt that smaller form of D. 
denticulata described above as f. jucunda, and A. formosum, based on LINDEN 2115, 
according to authentical specimens is identical with A. cubense Kuhn (Wricut 1099). 
But the matter is still more complicated; F&r also quotes LinpEN 2115 under A. 
jucundum and illustrates this species on pl. 42 fig. 1. This figure, although not very 
good, beyond doubt represents the Cuban form and is probably drawn after LINDEN 
2115; if A. jucundum were to be interpreted upon the basis of FEer’s figure, the 
name should be preferred for the Cuban species. Still it is evident that FEE has 
committed a double error in quoting LinpEN 2115 under A. jucundum and in using 
a Cuban specimen for the illustration of A. jucundum. | believe, therefore, that Mr. 
Maxon is right in interpreting the two proposed species of FEE on the basis of 
the descriptions, not of the figure, and consequently the Cuban species must bear 
the name D. formosa (Fée) Maxon.
